Abstract (en)

[origin: US2008266144A1] An encoding method includes a mapping for mapping a plurality of encoding sequences to a plurality of decoding sequences. Each of the encoding sequences includes at least one encoding symbol chosen from an encoding symbol set. Each of the decoding sequences includes at least one decoding symbol chosen from a decoding symbol set. The encoding method is characterized in that at least one of the encoding sequences includes at least two encoding symbols, and a predetermined shape changing type of a formal symbol in the encoding sequence is denoted by a latter symbol neighboring to the formal symbol, wherein the shape changing type including at least one of shape rotating, shape mirroring, shape deflating, stroke removal, cutting and notching.
